Serpent 811E Buggy Thread
#2041
Go Frank! Glad to meet you on Sunday and race with ya in Nitro buggy at least. Thanks for the help on the e-buggy setup too, I will switch the rear to hard/white springs.
At least you got to see the Thunder Tiger S3, the original car and original RB Worlds S7 motor, in action. I finished 5th, right behind you.
I will probably have it out there at Norcal Hobbies 1 more time, before I bring out my spankin new S3 with the long chassis conversion. Will be racing it in the Norcal Champs series this summer... in addition to my new Serpent.... but I really need to find someone to fuel me... no more running down the drivers stand

I want to try some of that Cold Fusion fuel too, if you bring some, I'll buy a gallon!

Im working on setting up a Y connector for my 2s batteries that connect to the esc.
Im using Deans connectors and I "think" that the batteries connect via Neg to Pos. between the batteries themselves and then, the one Pos. and one Neg. on respective batteries connects to the esc.
Im going to use two Deans connectors that are hard wired to my esc, so this pic has the closest example, but I cant tell which sides of the batteries are Pos. and Neg.
thanks for any pics, diagrams or "clearly" written explanations before I connect my esc and test out my radio... I read the Tekin manual and it specifically states that if I fry the esc from connecting it backwards, then it voids the warranty..
I got the wiring to the motor figured out, that was easy, clearly outlined in the esc manual, but there is more than one way to wire this Serpent!

Are you using hard packs? If so don't use any deans at all. Just put banana plugs on the end, and plug them directly into the battery. Then make a banana plug connector to wire 2 in series..
#2045
Ok, so how does the "series" part work.. thats what I really want to know more about.
whether its Deans or banana's the actual connector isn't too big a deal, I just wanna make sure I have the right Pos to Neg connections setup both between the 2 batteries and then to the Esc itself.
I have 2 hard packs now, but they both already have Deans on them.
I order 2 more hard packs, that will take banana connectors. This will be the setup going forward and the other 2 packs that already have Deans, will become my nitro starter box batteries and replace the NiMh packs to get more punch

1 2 3 4

so if your batteries look like that, 3 and 4 go to esc, and 1 and 4 get connected together.

How the adapter is wired also gives you a guide on how to wire up the hard case batteries.

Hey guys...I am new to the forum and 1/8 racing. I just bought a new Cobra-Be / 811-Be. I plan on going back and reading through the pages, but for times sake, could you guys give me any inside info on things to do/don't do, or to look out for during the build and setup?
Also, good parts to have as spares/upgrades?
Thanks!

the Be (electric version) has ALL the updated parts.. no need to get the V2 parts, the kit already has them all..
as for the build itself... one big word of advise...
CLEAN EVERYTHING WITH MOTOR SPRAY .. or brake cleaner
there is an oil residue on ALL parts, so clean them first, them start normal assembly using threadlock when needed.
One big issue with 1/8 is that anything and everything comes loose, so if in doubt, LOCKTITE IT!
- use grease on screws going into plastic, makes easier to assemble.
- use threadlock on setscrews that go into plastic.
- dont over tighten the sway bar ball mounts on the a-arms, it causes binding when moving the suspension arms.
- follow the instructions EXACTLY... yes the drivetrain will be tight, it loosens up as it breaks in.
- get some springs and sway bars as extra tuning options.
- CA your drive axle boots on, fill them with grease first.
- DONT put your transponder UNDER the esc, put it on the steering servo, or the RX box.
- ENJOY!

Eliminate the deans connector, just solder direct to the bullet style connectors.
The connector will cause a little voltage loss and one more thing to go wrong. Those connectors do fail sometimes. I posted some pics to help you solder direct from esc to bullet connectors.
You also want the bullet connectors that have 1/2 the channel missing to make it easy soldering, and the wires to lay flat, but all 4mm bullet style will work. Make sure your wires are laid flat on the esc or the body will get in the way and you will need to resolver it.

A little disappointment I ran across. I have bought all the anti-roll bar wires and wire holders and the system is nice except the 2.7 wires DO NOT fit in the holes. They are useless, a waste of money I'm tempted to send back to Serpent with my complaint.
